Minerallac 39004D 1/4 x 1-3/4" Magnetic Hex Driver Bit for #6-8 Screws

Minerallac 39004D 1/4 x 1-3/4" Magnetic Hex Driver Bit for #6-8 Screws

The Minerallac 39004D is a 1/4 x 1-3/4" magnetic hex driver bit built for fast, secure fastening of #6-8 screws on electrical and general assembly work. Its magnetic tip grips the screw for one-handed, slip-free starts, while the standard 1/4" hex shank and compact 1-3/4" overall length let it drop straight into impact drivers, drills, and manual bit holders. Whether mounting device plates, securing enclosure covers, or assembling panel hardware, this bit delivers a consistent, repeatable fit on #6-8 fasteners. It's a practical, everyday driver bit for electricians, contractors, and maintenance technicians who need a dependable fit on #6-8 hardware.

Key Features

• Trade Size: 1/4 x 1-3/4" bit dimension sized to fit standard 1/4" hex-shank power tools, impact drivers, and manual bit holders.
• Screw Compatibility: Precision-sized for #6-8 screws, giving a snug fit that helps reduce cam-out and stripped fastener heads.
• Magnetic Tip: Integrated magnetic tip holds the screw securely on the bit tip for one-handed, slip-free driving, even in overhead or awkward positions.
• Compact 1-3/4" Length: Short overall length provides access to recessed screws and confined electrical boxes, panels, and enclosures where longer bits can't reach.
• Standard 1/4" Hex Shank: Quick-change hex shank drops into most drill/driver chucks and quick-release bit holders without requiring an adapter.
• Consistent Torque Transfer: Hex shank design resists cam-out and bit slippage, helping maintain full torque transfer from driver to screw.
• Jobsite-Ready Durability: Compact hex bit format is easy to carry in a pouch or bit case alongside other 1/4" hex-shank accessories.
• Single-Bit Convenience: One dedicated #6-8 hex driver bit keeps a consistent, repeatable fit on the job instead of hunting for the right tip in a mixed bit set.
